To all whom it may concern lie it known that I. ALEXANDER S. Susan, a citizen of the United States, and resident of ("hicagm county of Cook. and State of Illinois. have invented certain new and useful Improvements in RoofingMachines, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to machines for making prepared roofing and more particularly to a machine for cutting so-called slab shingles from a continuous well. The object of the invention is to provide a machine which, while being rapid in operation, serves for cutting the shingles accurately to a uniform size and shape and which permits a ready removal of the cutting blades for sharpening or renewal. The invention is exemplified in the machineto be hereinafter described and which is illustrated by the accompanying drawings, wherein- Figure 1 is a plan view of the in'iproved machine, 7

Fig. 2 is a detail sectional view taken centrally through the cutting rolls but with some of the parts shown in elevation.

*iiidiciged at. 15 (Fig. 6).

Fig. 3 is a plan view showing a form of slab shingle which may be produced by the machine,

Fig. 4 is a longitudinal sectional view taken on the plane indicated h the line 44 on Fig. 1, but also showing the work in its passage through the machine.

Fig. 5 is a detail side view of the machine with the driving pulley omitted and the drive shaft shown in section, and

Fig. 6 is a plan view showing a detail of the web of prepared roofing with the cu ting operations of the machine indicated thereon by dotted lines.

The particular machine illustrated in the drawing may he used for cutting a continuous web, as 10, of prepared roofing. either into roofing: slabs, as 11, (Fig.3) with a serrated weather edge 12 and interlocking ends, 13, 14, or for cutting the said web into continuous roofin strips having; the said serrated edge. vghen the said continuous strips are'to he formed the web 10 is merely -divided longitudinally upon the sinuous line When the slabs, as 11,- re-to he formed, additional cuts. as 16 and 17, are made at intervals transversely through the parts of the web 10 at each side of the sinuous line 15. In order the the two ends 13. 14, of each slab 11 may have interlocking shoulders, as 18 and 19, each of the cuts 16, 17 comprises relatively oflset end portions 20, 21 and an intermediate oblique connecting portion 22. It will be observed from Fig. 6 that the lateral cutters operate at a. projecting point of the sinuous line on one side and at an indented point on the opposite side. Manifestly the longitudinal cut need not be sinuous, but may follow the lines of a truncated cone.

All of the cutting operations of the machine are preferably performed by a pair of cooperating rotary cutting rolls generally designated 23 and 24. As shown, the axes of these rolls are respectively located above and below the plane of a flat table 25 and the web 10 travels continuously over the table for movement between the rolls. The

continuous travel of the web is conveniently" accom lished by a pair of feed was 26 na- 27. hese feed rolls extend transversely above and below the surface of the table 25.

for engagement with the web 10 in advance of its engagement by the cutting rolls 23, 24. A pair of side frames generally designated 2 and 29 provide supports for the table 25. These frames )referahly also provide beariugs at each side of the table both for the shafts. as 31. 32,'up0n which the cutting rolls 23 and 24 are mounted and for the feed rolls .36. 27. A guideroll 30 may also be supported between the side frames 28. 29, at one end of the table for engagement with the weli'lO as it travels to the table.

The cutting rolls 23 and 24 are preferably of similar but mating construction. As showmeach cutting roll comprises an intermediate cylindrical portion 33 with a lateral extension 34. 35, at each side. A substantial construction is provided by forming the intermediate cylindrical portion 33 with a. central hub 36. When so formed, one end of the cylindrical portion 38 is integrally connected with the hub 36 by a Web 37. Under these circumstances that end of the cylindrical portion 33 which is remote from the web 37 is formed with a sinuous cutting edge 38. These ,cutting edges of the two rolls 23. 24 cooperate in shearing relation for longitudinally dividing the web 10 upon the sinuous line 15. ()u the other hand. the transverse cuts 16 and 17 are formed in the web by mounting cooperatin shearing blades cutting rolls 23, 24

the hub 36 beyond about the shaft by clamping M and 40 upon the laterai'extcnsions 34 and iii) respectively.

The two sets of blades 39, 4;), cooperate in alternation but 'not at regular intervals.

indentation 12 and thisedge of the formed with an even It follows are not located exactly infdiametrieally opposite positions with respect to the axis of the corresponding s aft 31 or 32 That is to say, the cutting rolls 23, 24, turn through a less angular (118- tance between ting 40 of the head 24 and the cooperation of the blade 39 of the cutting ,olade 40 of the cutting tween the cooperation of the last two men tioned blades with those first When the slabs 11 are to be formed with interlocking en ridge ofeach, blade 39, 40 is offset intermedithe cooperation of the cutblade 39 of the head 23 with the blade head 24; with the head 23 than bementioned.

ds 13, 14, as shown, the cutting ate its ends, as at 41, (Fig. 1.) The shearing cooperation of the blades 39, 10, accordingl serves to make the cuts 16, 17, upon the molten lines already described.

As the web will usually be provided with a gritor sanded surface, the cutting o erations require the application of considerable force and a stout construction is essential. The extensions 34 and of the should accordingly bu firmly supported upon the wrresponding shaft 31 or 32. Such a support is readily rovided for the extension 34 by continuing the web 37 from the cylindrical portion 33 of the corresponding roll and providing this part of the hub 36 with a web 42 which connects with the extension 34. The extension 35, on the other hand, is supported only at its ends. As shown, this extension 1S formed integral with the corresponding cylindrical portion 33. at one end. ts other end is carried by a fiparate hub 43, mounted upon the corres'p ding shaft 31 or 32 at a distance from the 36. Each cutting roll 23, held upon the'curresponding shaft 31; 32, by centrally dividing a part of the hub 36 at one side of the web 37 two halves of: such divided part of the hub bolts, as :14. 'lh web 42 and extension 34: are, however, preferably formed integral with-that part of th "hub 36 which is also. integral with the web 37 and cylindrical portion 33.

The blades 39 and 40 are preferably reinovably held upon the extension 34 and 35, as by screw bolts t5. These blades are, therefore, easily removed. for sharpening and when it is desired to o '1cratc the machine for the production oi continuous roofting blades 39,

" cutting and conn ecting the ing strips it is only necessary to remove one et of thcse blades. Inasmuchas the out 40, which are associated with the up or cutting roll 23 are more readily acccssi ile, the blades of this set will usually be removed for the production of the continuous roofing strips. To prevent displacement oi the blades 39, 40, it is i1nportaut that the extensions 34 and 35 should be provided with shoulders for engagement with the rear ed es of the blades. As shown, such a shou der is integrally formed upon the'extension 34, as at 46, (Fig. 4:).

0 provide a similar shoulder for the blade 40 a separate piece 47 is bolted against one side of the extension 35.

In order that the cutting rolls 23, 24, may be uniformly driven in opposite directions, the shafts 31 and 32 are geared together, as by intermeshing gears 48 and 49 located at one side of the table 25. The feed rolls 26 and 27 are preferably also geared together, as by intermeshinggears 50 and 51. The parts are driven in any convenient manner as b the application of a belt pulley 52to the s aft 32. When the gears 50 and 52 are located at the same side of the table 25 with the gears 48 and 49, motion is readily communicated to the feed rolls 26, 27 through an intermediate gear 53which meshes with the gears 49 and 51.
